Overview: High Efficiency 2 Phase Booster LED Driver for Automotive Front Lighting
NCV78902
The NCV78902 is a single−chip and high efficient two phase Booster designed for automotive front lighting applications like high beam, low beam, DRL (daytime running light), turn indicator, fog light, static cornering, etc. The NCV78902 is in particular designed for high current LEDs and with NCV78935 (triple channel Buck) or NCV78925 (dual channel Buck) provides a complete solution to drive multiple LED strings of up−to 60 V.
The device integrates a current-mode voltage booster controller, realizing a unique input current filter with a limited BOM. The available output voltage can be customized. Two devices NCV78902 can be combined and the booster circuits can operate together to function as a multiphase booster (2-phase, 3-phase, 4-phase) in order to further optimize the filtering effect of the booster and allow cost effective dimensioning for mid to high power LED systems.
Thanks to the SPI programmability, one single hardware configuration can support various application platforms.
